Abstract

This study assesses the dehumidifying performance
of the high efficiency residential central air conditioners
(CAC) in hot/humid climates typified
by that of Houston and Galveston. The performance
study is based on such factors as: (i)
weather (ii) thermostat set point and dead band,
and (ill) sizing of unit relative to the design load
of the residence. The units are evaluated on their
ability to maintain conditions in the ASHRAE
comfort zone in a typical residence in Houston
area. The units, the thermostat, and the residence
are simulated on a minute-by-minute basis
using a commercial software (TRNSYS) after
making certain modifications to it.
